ENCODING/DECODING METHOD AND DEVICE BASED ON DOUBLE PREDICTION

摘要

An encoding/decoding method and device based on double prediction are provided according to embodiments of the present invention. The method includes the following steps: After double prediction parameter information in a double prediction procedure is obtained, the double prediction parameter information is encoded according to a pre-established probability model, and an encoding result is written into an encoded code stream. Correspondingly, at a decoding end, after the encoded code stream corresponding to the double prediction parameter information in the double prediction procedure is obtained, the encoded code stream corresponding to the double prediction parameter information is decoded according to a pre-established probability model, so as to obtain the double prediction parameter information. As the encoding/decoding operation is performed based on the established corresponding probability model, the encoding performance on the double prediction parameter information in the double prediction procedure is effectively improved, and the transmission bandwidth occupied by the encoded code stream is reduced.
